These deadlocks can occur in multi-threaded environments when the usual delegation model is bypassed. Consider the situation outlined in Figure 1.
这些死锁可以发生在多线程环境中当常用的委托模型被忽略时。
Because the identities of the deadlocked class loaders are known, it is possible to examine the delegation model that these class loaders are using.
因为死锁的类装入器的标识已知，所以可以检查这些类装入器使用的委托模型。

In this case, the delegation model is a proper graph (with cycles), and so a deadlock can occur as a result of particular class relationships and thread usage.
在本例中，委托模型是一个正确的图(带有循环)，所以死锁的发生可能是使用特定的类关系和线程的结果。
When it comes to developing a rich and interactive user interface, Cocoa has always excelled. This is partly because of the flexible delegation model that it provides.
需要开发一个交互式富用户界面时，Cocoa总是技高一筹，部分原因是它提供的灵活的代理模型。
As with explicit class loading, if the class is already loaded, then a reference is simply returned; otherwise, the loader goes through the delegation model to load the class.
与显式类装入一样，如果类已经装入了，那么只是返回一个引用；否则，装入器会通过委托模型装入类。
The grantor of the delegated roles should be responsible for the usage of them, so constraints on the usage of the delegated roles are critical components of the whole delegation model.
角色委托者要对委托角色的使用负责，所以对委托角色进行使用限制是整个模型的关键组成部分。
To satisfy various restricted delegation requirements of actual applications, on the basis of the existing works, a Hierarchical Role-based restricted delegation Model (HRRDM) was proposed.
针对实际应用中对委托限制多方面需求的实际，在已有工作的基础上，提出了基于层次角色的受限委托模型HRRDM。

Currently, there are some models that extend RBAC model to support role delegation. However, their supports for constraints on the usage of delegated roles are very limited.
目前已有一些模型扩展了RBAC模型以支持角色委托，但是这些模型对委托限制的支持非常有限。
The paper puts forward a delegation logic based access control model (DLBAC). It translates the credentials, RBAC elements and access policies into unified delegation logic rules.
提出了一种基于委托逻辑的访问控制模型——dlbac，将凭证、RBAC元素和访问策略转化为统一的委托逻辑规则。
The core of this model is the recommendation-based trust model, organized as a trust delegation Tree (TDT), and the authorization delegation realized by delegation certificate chains.
这个模型的核心是基于推荐的信任模型，被组织成信任授权树(TDT)，并以证书链的形式进行授权。
